In the garage......again!!

Iv'e had a few issues now where the heat from the engine, especially around the manifold, has heated up the boost tube pipe, this has caused it to collapse under vacumm and melt together. Just wondering if the silicone tubing does the same, what does everyone else use?

Plain black rubber hose always works best.

Dont like much of that silicone stuff either. It will split or burst long before proper black rubber hose will.

looked on the bay, there is some 4mm inside dia silicone, but i dont think the outside diameter is up to the job only being 2.5mm wall thickness, will have a look for some rubber hosing.

jeez that's hectic !

That's very basic stuff for a motor factors to keep. I really dont know how any mechanics over there get any work done.
I see people asking where to buy xyz all the time on English forums. When it is all daily use stuff.

I can walk into any local factors, and they would all stock such stuff. They would useless if they didnt. And virtually none of them are big shops, just small ones.

Even Halfords would carry a range of hoses, although probably short sections at ridiculous prices.

These new modern turbos with their quick spool up time, would make the competition harder.

Wont really matter much, but generally it does not need to be big. Depends on hose size, and orifice feeding the hose.

If both are big and the gauge is undamped, you can get a rattly gauge or a vibrating needle. If the orifice is small and a large hose, the response may be slow as it has to "fill" the hose before it responds.

So smaller hose is generally better. Ive used 4mm OD hard nylon tubing in many cases. Very cheap, and if you use it with appropriate pneumatic fittings, it's dead easy to install and remove.
And if needed, 4mm rubber hose just pushes over it as required.
Any pneumatics place will sell the nylon tube. £10 should get 30m

If you do end up with a rattly or undamped gauge. Stick a small restrictor in the signal line somewhere. 0.6-0.8mm is ideal. It will damp out any pulsing.

You nearly always get a reasoned response on here if you ask the right questions - its what makes the site so good.
